mcsf

Port modification wrapper for ConfigServer Security&Firewall

Installation

gcc is required and so are python headers. They can easily be installed by using your distro package manager in most cases.

Debian/Ubuntu based

$ sudo apt-get install gcc python-dev python-pip
$ sudo pip install mcsf

Redhat and CentOS

$ sudo yum install gcc python-devel
$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python get-pip.py
$ sudo pip install mcsf

Usage

Things to note: When mcsf makes changes to the configuration file, a backup is made with CONFIGFILE.backup.

Pull up help documentation

$ mcsf --help
